Morphy against Löwenthal — the second game of their 1858 London match (King's Gambit Declined).

1. 10.g4 Premature. B. to K. Kt's 5th would have been correct play.
2. 12…hxg5 Black has now obtained a free range for the King's Rook, which promises subsequently to become a material advantage to him.
3. 13…d5 The best move.
4. 14.Bb3 This also is the right move; for if 14. P. takes P., P. to K's 5th 15. Q. to Kt's 2nd, Kt. to K's 4th, and White's position seems nearly hopeless.
5. 15…a5 Bringing the Queen's Rook into action, and thus adding to the strength of the attack.
6. 16.bxa5 The capture of the Pawn was compelled, for if the Knight's Pawn had been supported with the Rook's Pawn, in the exchange White would have been obliged to take with his B's P., when Black might have brought his B. to Q's 5th, with marked effect.
7. 16…Rxa5 Black's pieces are now in full play, and he has an excellent game.
8. 21…Rb2 This, as the result proves, was an erroneous sacrifice.
9. 26…Qa3 Kt. to B's 5th would have been the correct play.
10. 27…Bc7 An unaccountable blunder, to occur in a match game.
